2 questions

Hey! I have two questions. Does anyone remember an old movie from like maybe the seventies or eighties about a bunch of kids who play with a ouija board & then get killed? Also I seem to remember a piece of a movie about a man who either died & went to hell & came back or was killed in an experiment & brought back & had been to hell & he was insane? Does anyone remember this? I seem to remember him in a big glass chamber with a puppy or a goat or a lamb & he literally tore it to pieces with his bare hands. It scared the crap out of me & I just wonder if anyone else saw it? Thanks!
